Time：2022-03-29 11:00 — 12:00 Location：Edinburgh Coffee House Speaker：Dr. Ian Mackie (University of Sussex) Overview ▶ Very simple GOI for System T. ▶ Reversible machinery for higher-order language. ▶ Depending on how we constrain the use of the recursor, this language is rich enough to capture all primitive recursive functions or more generally Gödel’s System T.

Making Concurrency Functional by Glynn Winskel   http://arxiv.org/abs/2202.13910   The article bridges between two major paradigms in computation, the functional, at basis computation from input to output, and the interactive, where computation reacts to its environment while underway.  Central to  any compositional theory of interaction is the dichotomy between a system and its environment.  Concurrent […]

James Wood and Robert Atkey. A Framework for Substructural Type Systems. ESOP 2022, to appear. 2022. [BIB] [PDF] Abstract Mechanisation of programming language research is of growing interest, and the act of mechanising type systems and their metatheory is generally becoming easier as new techniques are invented. However, state-of-the-art techniques mostly rely on structurality of the type system — […]

ath.CT String diagrams for non-strict monoidal categories Authors: Paul Wilson, Dan R. Ghica, Fabio Zanasi Abstract: Whereas string diagrams for strict monoidal categories are well understood, and have found application in several fields of Computer Science, graphical formalisms for non-strict monoidal categories are far less studied. In this paper, we provide a presentation by generators and relations of string […]

Effect handlers allow for programming with user-defined computational effects, with applications including custom lightweight concurrency (threads, async-await, actors, generators), error handling, dependency injection, etc. Effect handlers originate from the realm of functional programming, and the main goal of this highly experimental library is to explore how they fit in the more object-oriented setting of C++. The library relies […]

The Programming Language Laboratory of the Huawei Edinburgh Research Centre are delighted to start a new research project with Prof. Phil Wadler from the University of Edinburgh on the topic of type systems for effect handlers.  The project will focus on simplifications static scoping of algebraic effect handlers and on developing gradual types for the […]

OpenMP Taskloop Dependences Authors   Marcos Maroñas Bravo (Huawei Edinburgh RC, Programming Languages team) Xavier Teruel Vicenç Beltran Abstract Exascale systems will contain multicore/manycore processors with high core count in each node. Therefore, using a model that relaxes the synchronization, such as data-flow, is crucial to adequately exploit the potential of the hardware. The flexibility of the […]

Our new team member Giulio is giving an invited talk at LSFA, an FSCD-associated workshop. More details on the workshop web page: https://mat.unb.br/lsfa2021/pages/invited.html Understanding the lambda-calculus via (non-)linearity and rewriting.Abstract: The lambda-calculus is the model of computation underlying functional programming languages and proof assistants. Actually, there are many lambda-calculi, depending on the evaluation mechanism (e.g., […]

Speaker: Prof. Vincent Danos, Ecole Normale Paris Title: “Decentralised Finance the Old and the New” Date/Time: 2021/06/17 9:30 Recording: https://youtu.be/ysc5KSeDQOQ Abstract What is so special about decentralised finance? What kind of assets are traded and what is their fundamental value? What kind of basic financial primitives are available, and can they be combined? We will […]
